A great blue heron is after my koi! My pond has straight sides and ranges
in
depth from 2 feet to 3 1/2 feet. He's been by pond but not in it so far
and
I've chased him away. Any suggestions to keep this feathered pond raider
from eating my koi? Help fast please!!!

Some takes or posts in the grownd around the pond but angled in over the
surface of the water & then run wire/string around them to form a fence that
overhangs the water. Don't give him anywhere to land that allows him to then
walk into the pond or stand beside the edge of it.
